Types of Rocks
Sedimentary Rocks
Metamorphic RocksIgneous Rocks
Sedimentary Rocks rock that forms from sediment
• Wind and water break down the earth• This is the process of weathering.

• Layers are formed and build up• Pressure and time turn the layers to rock
• Bits of sediment settle in lakes and rivers• This is the process of Deposition.

Fossils are found in sedimentary
rock.
Igneous Rocks – forms when lava or magma cools and hardens
• Fire Rocks
Metamorphic Rocksrocks that form when sedimentary and igneous
rocks change under pressure and heat
• Rocks that have changed• They were once igneous or
sedimentary• Pressure and heat changed the rocks
• Rock cycle – the changing of rocks over time from one type to another
